junior

Update this junior-prod app to the latest published Junior release. Use when asked to self-update Junior, bump @sentry/junior and @sentry/junior-* dependencies, run safety checks, and open a draft PR.

Work with GitHub repositories, source code, branches, commits, pushes, pull requests, reviews, diffs, and CI runs. Use for repo implementation tasks, source-code investigation, cloning/fetching, branch and push workflows, PR creation, PR updates, PR review feedback, and GitHub Actions checks. Prefer this skill for repository and code tasks even when the repo concerns Sentry products.

Validate Junior changes through local app-facing paths. Use for local client or agent QA, dashboard mock reporting UI QA, PR readiness, plugin CLI commands, skill/tool/prompt/plugin behavior, and behavior that tests do not cover well but can be exercised with `pnpm cli -- chat ...`, `pnpm cli -- <command> ...`, or `JUNIOR_DASHBOARD_MOCK_CONVERSATIONS=true pnpm dev`.

Query read-only Amplitude product analytics. Use when users ask about active users, product usage, events, segmentation, funnels, conversion, retention, charts, dashboards, experiments, cohorts, taxonomy, session replay, feature flags, guides, surveys, feedback, agent analytics, or individual user activity in Amplitude. Do not use for changing Amplitude charts, dashboards, experiments, cohorts, flags, taxonomy, or project configuration.

Use for subscribed GitHub pull request events involving the local headless PR fixture repository.

Create, update, comment on, label, and inspect GitHub issues with concise, evidence-backed content. Use when users ask to open, edit, view, close, reopen, or triage GitHub issues — including tracking bugs, features, or tasks. Prefer this skill over generic repository tools for issue operations; do not use for pull requests, branches, pushes, or PR creation order questions.

Manage Linear issues through Linear's hosted MCP server. Use when users ask to create a Linear ticket, update a Linear issue, add a Linear comment, move work between states, assign work, or look up Linear issue, team, or project details from Slack context.

Build, review, or update Junior extension skills and plugins. Use when users ask to create a Junior SKILL.md, app skill, plugin, plugin.yaml, packaged plugin, MCP-backed plugin, OAuth or credentialed plugin, or to validate Junior extension files. Do not use for ordinary Junior usage, provider workflows, generic code editing, or non-Junior agent-skill authoring.

Automate websites with the agent-browser CLI for navigation, form flows, screenshots, extraction, and repeatable browser tasks. Use when users ask to interact with web apps, gather evidence from pages, or run browser-based QA steps.

Author Slack HTTP integration tests using the repository MSW harness and fixture factories. Use when asked to add a Slack integration test, mock Slack API calls with MSW, test Slack action HTTP behavior, or assert Slack request payloads in tests.

Cloudflare production operations via the Cloudflare API MCP server. Use when users ask to investigate Workers errors or performance, check build or deployment status, query logs, inspect DNS records, check load balancer pool health, review Zero Trust tunnels, or manage Cloudflare resources. Do not use for Sentry issues, GitHub/Linear ticketing, or non-Cloudflare infrastructure.

Use for eval coding fixture tasks involving the small TypeScript project under skills/coding-workspace-fixture/project.

Use for `/eval-auth` requests in auth-resume evals. Always connect through the disclosed MCP tool before answering, then continue the user's actual request using prior thread context when needed.

Use for `/eval-mcp` requests that need the eval MCP handbook lookup.

Use for `/eval-oauth` requests and eval-oauth account connect, reconnect, or auth-flow test requests. You must run the eval identity check before answering anything else.

Looks up candidate data via a Python script and formats it into a brief. Use when users invoke /candidate-brief with a candidate name.

Lists files in the sandbox working directory for eval verification. Use when users ask to "list files in the working directory", "show files here", or invoke /list-working-directory in eval scenarios.

Use for /resilient-working-directory eval requests that verify command interruption recovery.

Check bundled source handbook files for capability, policy, or implementation verification questions. Use when users ask to double-check or verify what the internal/source handbook says.

Look up current weather conditions for a city. Use when users ask about weather, temperature, or forecast for a location.

Internal data access primitive. Executes a Hex query and returns structured results. Called by core skills — not intended for direct use. Invoke when you need to run a Hex query on behalf of a core skill that has provided a query and pattern. Do not use for Sentry product telemetry, Sentry feature-usage questions, or explicit requests to use Sentry telemetry when the Sentry skill is available.

Query live Sentry telemetry with the Sentry CLI and generate Sentry deep links. Use when users ask to investigate Sentry issues, events, logs, traces, organizations, projects, replays, product feature usage, Sentry's own product telemetry, or authenticated Sentry API data. Do not use it for repository/source-code/PR tasks, even when the topic concerns Sentry products.

Manage low-level config and plugin introspection flows via jr-rpc bash commands. Use only when the user explicitly asks to read or update provider defaults/config or list installed plugins. Do not use for PR, branch, push, or auth-order questions; load the matching provider skill instead.

Integrate the latest `@earendil-works/pi-agent-core` APIs into an app, library, runtime, or agent harness. Use for Pi `Agent`, `AgentHarness`, streaming bridges, tool execution hooks, `convertToLlm`/`transformContext`, queueing via `steer`/`followUp`, `continue()` semantics, `streamFn`/`streamProxy`, timeout/abort, session, skill, or compaction behavior.

Query Vercel deployments, build logs, runtime logs, and deployment status through the Vercel CLI. Use when users ask to debug Vercel deployments, inspect failed builds, fetch production or preview runtime logs, find a deployment for a project or commit SHA, or investigate Vercel-hosted app errors. Do not use it for deploying, rolling back, changing project settings, domains, env vars, caches, storage, or any other Vercel mutation.

Query live Datadog telemetry (logs, metrics, traces, spans, monitors, incidents, dashboards, services, hosts) through Datadog's Pup CLI. Use when users ask to investigate production behavior in Datadog, including searching logs, checking monitor status, inspecting traces or spans, looking up incidents, finding services, or correlating metrics. Do not use it for Sentry issues, repository/source-code work, or ticketing.

Search Notion pages and data sources and summarize the best match. Use when users ask to look up docs, specs, notes, meeting notes, project context, roadmaps, trackers, or internal references stored in Notion.

Use for `/eval-auth` requests in MCP auth-resume integration tests. Always connect through the disclosed MCP tool before answering, then continue the user's actual request using prior thread context when needed.

Implement Slack bot behavior with correct Slack-documented message formats, inbound mention/event routing, and long-running task UX. Use when asked to "format Slack messages", "fix Slack markdown", "debug thread mentions", "improve Slack bot UX", "add streaming in Slack", or "build Slack Chat SDK behavior". Covers mrkdwn quirks, Events API payload patterns, routing guardrails, and Chat SDK implementation patterns.

Investigate Vercel Sandbox lifecycle, timeout, snapshot, and persistence behavior. Use when users ask about Vercel Sandbox, `@vercel/sandbox`, `Sandbox.create`, `Sandbox.get`, why files disappeared, how snapshots differ from persistence, or whether Vercel's persistent sandbox beta applies.

Build and deploy universal JavaScript servers with Nitro v3. Use when working with nitro.config.ts, defineNitroConfig, defineHandler, defineConfig, server.ts entry, filesystem routing, route rules, useStorage, defineCachedHandler, useDatabase, definePlugin, runtime hooks, Vercel/Cloudflare deployment, or migrating from Nitro v2/nitropack.

Create and maintain public, user-facing product documentation for this repo's `packages/docs` app. Use when asked to write, revise, or review docs pages (tutorial/concept/reference/troubleshooting), improve docs information architecture, fix docs frontmatter/linking issues, or align docs quality with Vercel/Sentry-style standards.

Explain plugin-bundled skills in this example app. Use when users invoke /example-bundle-help.

Provide a compact local example response. Use when users invoke /example-local.

Build and operate Vercel Queues with @vercel/queue across push and poll consumers. Use when users ask about "vercel queues", "@vercel/queue", "queue/v2beta", "handleCallback", "PollingQueueClient", "receive", queue retries, visibility timeouts, idempotency keys, or queue region routing.
